藜麦蛋白的提取工艺优化

Optimization of Extraction Process of Quinoa Protein

摘要: 藜麦被认为是一种伪粮。藜麦蛋白和其他谷物相比，赖氨酸和蛋氨酸的含量更高一些，因此，越来越多的研究将注意力集中在藜麦蛋白质的营养价值和作用特点上。本研究采用了超声辅助碱法作为提取蛋白的关键技术。为进一步确定最佳提取条件，我们实施了系统的单因素试验，并结合了响应面法进行优化。经过分析与实验验证，最终确定了藜麦蛋白提取的最佳工艺参数：即原料与提取液的比例为1:15，超声处理的功率设定为1080 W，温度为40摄氏度。在此条件下，藜麦蛋白的得率高达60.056%，实现了高效的蛋白提取效果。本研究通过优化提取工艺，有助于深入探究藜麦的潜在营养价值，更好地为人类服务。

Abstract: Quinoa is considered to be a fake grain. Quinoa protein has higher levels of lysine and methionine than other cereals. Therefore, more and more studies have focused on the nutritional value and functional characteristics of quinoa protein. In this study, ultrasonic-assisted alkali method was used as the key technology for protein extraction. In order to further determine the optimal extraction conditions, we carried out a systematic single-factor experiment and combined the response surface method to optimize. After analysis and experimental verification, the optimal process parameters of quinoa protein extraction were finally determined: the ratio of raw material to extract was 1:15, the power of ultrasonic treatment was set to 1080 W, and the temperature was 40 degrees Celsius. Under these conditions, the yield of quinoa protein was as high as 60.056%, which achieved efficient protein extraction. In this study, by optimizing the extraction process, it is helpful to explore the potential nutritional value of quinoa and better serve human beings.
